An infrared image on April 14 at 0517 UTC (2:47 p.m. Australia/Darwin local time) from NASA's Atmospheric Infrared Sounder (AIRS) instrument (that flies aboard NASA's Aqua satellite) shows that Tropical Storm Errol's strongest thunderstorms with the coldest, highest cloud tops were off-shore from the northern coast of Western Australia. Those thunderstorms had cloud-top temperatures as cold as or colder than -63 F/-52C and brought heavy rainfall.

Multispectral satellite imagery also showed a well-defined center of circulation in Errol, and bands of thunderstorms wrapping around its souther and western edges.
Tropical Storm Errol has sustained winds of 40 knots (46 mph/74 kmh) with higher gusts, and is kicking up rough surf along the northern coast of Western Australia today. Errol's center was about 270 miles (434 km) west of Darwin, Australia near 13.1 South latitude and 126.3 East longitude. Errol is currently drifting south-southwestward at 2 knots (2 mph/~4 km) but is expected to start moving to the west-northwest as a result of a strengthening ridge of high pressure building up over Western Australia.
Forecasters at the Joint Typhoon Warning Center (JTWC) take the storm westward and out to the open waters of the Southern Indian Ocean over the next couple of days, which is good news for residents of Western Australia. However, dangerous surf will continue with gusty winds and heavy downpours over the weekend as Errol moves away. Currently the JTWC notes that Errol is kicking up 12-foot (~3.5 meter) high seas.
The Australian Bureau of Meteorology (ABoM) noted that Errol may intensify on April 16 as it continues to move away from the Kimberley coast of Western Australia. ABoM has posted a Blue Alert for residents who live in areas between Kalumburu and Kuri Bay, including coastal and island communities. The ABoM forecast notes that wind gusts as high as 68 mph (110 kmh), just a little below hurricane-strength, may be experienced along coastal areas from Kalumburu and Kuri Bay later tonight (April 15) or Saturday (April 16) morning depending on the Tropical Storm's movement. Errol is also expected to bring heavy rainfall, so residents should be on guard for local flooding especially in the northern areas of the Kimberley.
Errol is forecast to track west into the Indian Ocean and remain south of the main Indonesian islands.

Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
